BleepingComputer.com: Slow Boot With Vista Home Premium

Am using Vista Home Premium on a new and reasonably high spec PC. Suffering from annoying hang on boot - total boot takes around 3 min when all start progs disabled - otherwise Vista appears to be running OK. Have cleaned out all temp files but still slow. Boots fast and without problem in Safe Mode so suspect a software driver loading problem (all hardware drivers checked and OK). Boot event log shows mainpathboottime of 157 secs - other main time components are bootexplorerinittime (74 secs), bootuserprofileprocessingtime (32 secs), bootprefetchinittime (28 secs) and bootpostboottime (23 secs). Bootlog (ntbtlog.txt) shows two pages of drivers but does not show how long each one took to load and so do not know which one(s) causing the delay. Does anyone have any idea what could be causing problem and can anyone recommend a bootlog analyser (THAT WORKS WITH VISTA) that would give me the individual driver loading time and sequence?

I'd start with "perfmon /report" at the Start dialog.
After that, go to Control Panel (Classic View)...Performance Information and Tools...Advanced Tools...View performance details in Event log
That'll give exact times for boot issues that exceed the norm.

Thanks John,
I really appreciate your help.

The perfmon/report showed no problems.

The event log shows this most days:

Error 09/03/2008 08:08:04 Diagnostics-Performance 100 Boot Performance Monitoring

Warning 09/03/2008 08:07:59 Diagnostics-Performance 200 Shutdown Performance Monitoring

Some times the following critical event message is shown:

I have reasoned that there must be a driver loading problem so have checked the boot log many times and the typical log is the following:

This was where I would have liked a boot log analyser so that I could see which drivers were taking the most time.

Any suggestions?

Process Monitor (free here: http://technet.microsoft.com/en-us/sysinte...s/bb896645.aspx ) can do boot logging - but I'm not familiar with it. This link may help: http://4sysops.com/archives/new-features-s...1-boot-logging/

I'd think it'd be easier to look at the warnings that are associated with the time that the boot occurred - but I'm still learning about this portion of error reporting in Windows.

John,
Process Monitor appears to have given me the data I need but the number of processes occurring during the 4 minute boot is awesome and so I now have a fair bit of analysis to do to identify which one of the many is causing the hang.
Many thanks

First thing I'd do is look in Services Applet (do Windows-R services.msc) and make sure
Superfetch is set to start type of Automatic. If it doesn't start up at bootup(for instance
if start type is Manual) you will get slow boots.

Another thing to try is open a command window and go to
c:\Windows\Prefetch\Readyboot
del *.*
then do cd .. to go up to Prefetch
del *.*

Windows will reload these prefetch directories with fresh data.

If you get an error trying to delete make sure the command window
had "Administrator" in the title. See the help for running console
command sessions as Administrator.

If none of that does any good, then you might use
WinPatrol to space out your application startups using
"Startup Delay" utility and see if one just takes a long
time(I guess there's a startup control built into Vista
but I've used WinPatrol for a while so I haven't checked
it out.)

I don't know if you can do this (haven't rebooted since I started Process Monitor - but you may be able to sort by time. Then it's just a matter of looking for a large gap in the times.

I'd still check the other entries in the Performance log around the time that Windows gave the error - that way you'll have a leg-up on what the problem might be. In my case a lot of the lag is due to Avast Antivirus starting - and it's increased as time has gone on.

Windows is doing lots and lots of stuff that you can't see - that's why the log is so complicated. There's things that you can do to streamline the boot process - but I'm still a beginner at that (still working on understanding the XP boot process).

Gentlemen,
Thanks for your comments. I have confirmed that superfetch is set to automatic. I have done a quick visual scan of the thousands of boot processes identified by Process Monitor but have not yet found anything obvious. I have, however, noted entries referring to work files (docs etc) I have not accessed for years and wonder why they should be being processed during boot. I have a friend who has virtually the same PC as me and much of the same software. His PC boots very fast and so he is going to run Process Monitor and then we will compare outputs to look for major differences. I am also going to time my boot with a stopwatch and correlate the precise times of the hang stages with the the precise times of the boot processes shown by PM - that should help me to narrow down which processes are guilty. I have also noted a lot of entries for Network Magic and Zone Alarm but the boot is not much quicker when both progs are disabled.

Disabling the programs may not affect the boot - it depends on how much time is spent looking for stuff vs. how much time is spent loading stuff. For example, in the old days, a mapped network drive that no longer existed would cause boot times to soar while Windows looked for things.

Try turning off (set to Disabled) Windows Indexing Service and see
what happens. (a good idea anyway unless you love to use Windows
search engine.)

Here is my Event Viewer information....this looks like an excessive amount of errors and warnings. Can anyone help me with this....I've been using Vista SP1 for less than a week and my boot/shut down/application load times have slowed to a crawl.

Thanks in advance,
Jon

While this tells us that your boot and shutdown times are bad, it doesn't tell us why.
There's a tool available for Vista that will help isolate this, but I'm not real familiar with it. It's called the Windows Performance Toolkit and is available for free from here: http://www.microsoft.com/whdc/system/sysperf/perftools.mspx
Also a part of this package is the On/Off Transition Performance Analyzer - which seems tailor made for this situation.
